Finally.. after so many reading and searching over the internet, I finally decided to build this antenna..
A 3 element short boom Yagi designed by L.B. Cebik, W4RNL. The design description can be found
The material I used is basically aluminium tubes available locally and some other parts are bought of the shelf which is a hydraulic hose clamp that I use to secure the elements onto the boom. This is necessary as all the elements are isolated from the boom.
